摘要

我们报告了巴西帕尔州圈养巴西貘(Tapirus terrestris)中发生的两例血色素沉着病样疾病。两种动物均表现出与含铁血黄素显著积累相关的慢性肝病症状。波尔图的颜色表明，在门静脉间隙的巨噬细胞、库普弗细胞以及门静脉周围区域的肝细胞中有明显的铁积累。马森三色显示明显的门脉纤维化。这种疾病在貘中的病理机制尚未很好地确定。有人认为，这些物种可能有不同的铁吸收和消除机制，使它们对饮食中铁含量的增加很敏感。在澳大利亚和苏格兰的动物园中有两个关于这种疾病的报道。根据组织病理学和组织化学发现，这是巴西貘中首次报告这种疾病。

Hemochromatosis-like disease in Brazilian tapirs (Tapirus terrestris) in Pará state, Brazil

ABSTRACT We report two cases of hemochromatosis-like disease in captive Brazilian tapirs, Tapirus terrestris in Pará state, Brazil. Both animals presented symptoms of chronic hepatopathy associated with marked accumulation of hemosiderin. The coloration of Perls demonstrated pronounced iron accumulation in macrophages in the portal space, Kupffer cells, and, to a lesser extent, in the hepatocytes of the periportal region. Marked portal fibrosis was evidenced by Masson’s trichrome. The pathological mechanisms of this disease in tapirs are not yet well established. It has been suggested that the species may have different mechanisms of iron absorption and elimination, rendering them sensitive to elevation in dietary levels of this metal. Two previous reports of this disease in T. terrestris exist from zoos in Australia and Scotland. This is the first report of this disease in tapirs in Brazil based on histopathological and histochemical findings.
